FUEL-DEFLECTOR FOR MECHANICAL STOKERS.

SPECIFICATION forming part of Letters Patent No. 789,486, dated. May 9,1905. Application filed June 17, 190 1. Serial No. 213,048.

To all whom it may concern:

Be it known that I, JOHN J. BURWELL, a citizen of the United States,residing at Central Covington, in the county of Kenton and State ofKentucky, have invented certain new and useful Improvements inFuel-Deflectors for Mechanical Stoker-s, of which the following is fromthe following description and claims and from the drawings, in whichFigure 1 is a perspective view of my improved device applied, partlybroken away for better illustration of parts. Fig. 9. is a centrallongitudinal section of the same on the line :0 m of Fig. 4, showing thedeflector in edge elevation in one position in full lines and in anotherassumed position in dotted lines. Figs. 3 and 4 are rear views of myimproved device, partly broken away, each showing the deflector in oneposition in full lines and in another assumed position in dotted lines.

The figures indicate a number of the various positions into which thedeflector may be thrown.

A represents the fire-box of a locomotive or may represent any suitablefurnace, to which a door B is hinged. The door has an opening (3, aboutwhich there is a thimble D on the door. The inner end of the thimble isindented, as shown at-(Z, for accommodating the stem of the deflector. Afuel-chute E is secured to the thimble, as by a pin 6 taking throughapertures in the chute and thimble, the thimble forming a continuationof the chute. The chute may at its other end connect with any suitablehopper, fuelconveyer, or stoker. It may have connection similar to thefuel-chute shown and described in my aforesaid patent.

F is a deflector and preferably comprises a deflector-plate f and a stemf. The stem passes through an opening 0 in the door. Thedeflecting-plate preferably has a concave side f and a convex side f andis arranged to have either of its sides presented to the mouth of thechute, thus making it reversible. hen the concave side is presented tothe mouth of the chute, it forms a channel along which the fuel may bedirected for being conveyed or projected to remoter parts of the furnaceor lire-box, dependent on the angle at which the plate is presented tothe mouth of the chute, as hereinafter explained. When the convex sideof the deflector-plate is presented to the mouth of the chute, a bulgedface is presented to said mouth and the coal is spread over a greaterarea in the lire-box, the part of the fire-box to which the fuel isconveyed being also in this case dependent on the angle at which theplate is presented to the mouth of the chute. A turning movement ispermitted the deflector-plate. Means are also provided for bringing thedeflector-plate closer to or farther from the mouth of the chute and forchanging the angle of the deflector-plate with relation to said month.In this manner the fuel may be directed to any part of the lireboX ordropped at the front part thereof, as may be desired.

G is a hanger. It comprises links g, pivoted on lugs ,r/ to the thimble,and a bearing to which the links are articulated, as at The bearing hasa rib 9, taking into grooves on the stem f.

A curved guide H is pivoted at 71 to the door B for permitting the guideto swing up and down. A spanner-piece I slides on the guide and has anaperture 2', through which the stem f passes. A set -screw ei takesagainst the stem through the spanner-piece and firmly secures the stembetween the setscrew and guide for fastening the parts securely inadjusted position. The stem has annular grooves f, into which the end ofthe set-screw and rib g may take for positioning the stem at variouspoints of its length on the guide. The stem has a handle f, by which thedeflector-platef may be manipulated. The stem may be movedlongitudinally for moving the deflector-plate toward or away from themouth of the chute or feeder E or turned upon its longitudinal axis forchanging the angle of the deflector-plate about its longitudinal axisand for reversing the said plate or turning it upside down forpresenting either its concave or convex side to the mouth of the chute.The stem may also be swung on the pivots of the hanger for throwing thedeflector-plate more or less upwardly in front of the mouth of thechute, and the curved guide may also be swung up or down on its pivotsfor aiding in this movement. The inner end of the deflector-plate may bethrown inwardly and upwardly sufficiently for receiving the fuel uponthe deflector-plate and directing it downwardly at the front end of thefire-box, and the indentation (Z in the end of the chute accommodatesthe deflector-stem for extreme position of this kind. The deflectorplatedeflects the fuel, which is usually in crushed state when fed throughthe chute, to any desired part of the fire-box.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. Ina mechanical stoker, the combination, with a fuel-chute, ofafuel-deflector comprising an integral deflector-plate and stem movablelongitudinally and to various angles with relation to said chute, andreversible for presenting either side of said deflector-plate to themouth of said chute.

2. In a fuel-deflecting device for mechanical stokers, the combination,with a fuelchute, of a fuel-deflector, and means permitting turning ofsaid deflector about its longitudinal axis for presenting either side ofsaid deflector to the mouth of said chute and positioning the deflectorat various angles to the front of the mouth of the chute, substantiallyas described.

3. In a mechanical stoker, the combination with a fuel-chute, of afuel-deflector having a deflector-plate with a plurality ofreceivingsurfaces of different shapes for the fuel, said deflector-platebeing movable in the direction of the plane of extension of saiddeflectorplate, to various angles with relation to the mouth of saidchute, and for presenting any of said receiving-surfaces to the mouth ofsaid chute.

4;. In a fuel-deflecting device for mechanical stokers, the combinationwith a fuelchute, of a fuel-deflecting plate having a channeled side anda bulged side, and means for presenting either of said sides to themouth of the chute.

In a fuel-deflecting device for mechanical stolrers, the combinationwith a fuelchute, of a fuel-deflecting plate having a channeled side anda bulged side, means for presenting either of said sides to the mouth ofsaid chute, and means for positioning said plate at various angles withrelation to said mouth, substantially as described.

6. In a fuel-deflecting device for mechanical stokers, the combination,with a furnace and fuel-chute therefor, of a fuel-deflecting platehaving a channeled side and a bulged side inside said furnace, saidfuel-deflecting plate havingastem connecting therewith from outside saidfurnace, means for supporting said stem, said supporting means havingpivotal connection with said stem, a curved guide, said stem beingadapted to have longitudinal movement with relation to said guide andmeans for positioning said stem longitudinally of said guide,substantially as described.

7. The combination, in a mechanical stoker, with a fuel-chute, of afuel-deflector reversible for presenting either of its sides to saidchute.

In witness whereof I have signed my name hereto in the presence of twosubscribing witnesses.
